摘要:
A battery pack for use as a backup power supply device for various electronic devices has a rechargeable battery group having a plurality of cylindrical rechargeable batteries connected in series and/or parallel and arranged in horizontal flat arrays as a flat block, and an electronic circuit for controlling charging of the rechargeable battery group. Two heat radiating plates sandwich opposite surfaces of the rechargeable batteries of the rechargeable battery group and are held against circumferential surfaces of the rechargeable batteries. A battery case houses an electronic circuit positioned at an end in the direction of the arrays of the rechargeable batteries and surrounds the rechargeable battery group to accommodate them therein. The battery case supports the heat radiating plates so as to be exposed to the exterior. The battery pack is compact and free of thermal problems with the rechargeable batteries.
摘要:
A rechargeable battery pack provided with a battery voltage detector for detecting a terminal voltage of a rechargeable battery cell, a nullnullV detection circuit or other full charge detecting means for detecting a full charge state when charging the rechargeable battery cell, a switch device interposed in a charge current circuit of the rechargeable battery cell and opening the charge current circuit when detecting a full charge state, a memory for storing a closed circuit voltage of the rechargeable battery cell immediately before the charge current circuit is opened, an internal resistance detection circuit for finding a value corresponding to an internal resistance of the rechargeable battery cell from an open circuit voltage and the closed circuit voltage stored in the memory after the charge current circuit is opened, and a lifetime indicating means for referring to a battery lifetime table in accordance with a value corresponding to the internal resistance of the rechargeable battery cell to predict the lifetime of the rechargeable battery cell and outputting information on the lifetime. This enables accurate determination of the lifetime of the rechargeable battery cell under stable conditions without wastefully consuming the charging capacity.
